1993年，在日本中部相模湾的菲律宾板块和北美板块之间的板块边界处部署了一个综合性长期深海底观测站，以研究与至少0.01Ma至今反复发生的地震群和海底火山喷发相关的地球物理参数之间的关系。它也位于水蛤（Calyptogena soyoae）的栖息地范围内，其存在表明从下方渗漏。该观测站位于初岛外海1174米深处，配备了地震仪、水听器、热流温度探头、彩色摄像机、CTD和海流计等多种传感器。初岛陆地站的数据和电力通过8公里长的光电电缆实时发送。截至 1996 年，收集了超过 3 年的深海海底连续地球物理和环境数据。在本文中，我们描述了该系统并报告了与邻近地区的三个地震群相关的地面温度的显着变化。 (C) 1998 年由 Elsevier Science B.V. 出版。保留所有权利。
A comprehensive long-term deep seafloor observatory was deployed at the plate boundary between the Philippine and North American plates in Sagami Bay, central Japan in 1993 in order to investigate the relations among geophysical parameters associated with earthquake swarms and eruptions of submarine volcanoes that have occurred repeatedly from at least 0.01 Ma to the present. It is also located within the habitat range of the vesicomyid clam, Calyptogena soyoae, the presence of which suggests seepage from below. The observatory, at a depth of 1174 m off Hatsushima Island, is equipped with multi-sensors, such as a seismometer, hydrophone, heat flow temperature probes, color video cameras, a CTD and a current meter. The data and power to and from the land station at Hatsushima Island are sent in real time through an 8-km-long electro-optical cable. More than 3 years of continuous geophysical and environmental data on the deep seafloor were collected up to 1996. In this paper, we describe the system and report on significant changes in ground temperature associated with three earthquake swarms in the adjacent area. (C) 1998 Published by Elsevier Science B.V.
